Abstract

The dynamic knee valgus (DKV) during different sport maneuvers has been widely described as risk factor to develop an anterior cruciate ligament injury. Hip and knee muscles seem to have a crucial role to prevent the dynamic knee valgus. This study aimed to give normative and correlational data about DKV and hip and knee neuromuscular response (NMR) among healthy active males. The hypothesis is that DKV could be correlated with hip NMR. A cross-sectional correlational study. Research Anatomy Laboratory. The study was carried out among 50 active, non-injured males. Dynamic Knee-Valgus angle and lower limb posterior chain muscles Neuromuscular Response. DKV was measured using Kinovea software during a Single-Legged Drop Jump test and NMR was measured using tensiomyography and myotonometry for gluteus maximum, biceps femoris, semitendinosus, lateral and medial gastrocnemius. Right and left limbs were both performed and analyzed independently. No significant correlation was observed between DKV and hip and knee muscles NMR. This study shows normative and correlational data about dynamic knee valgus, tensiomyography and myotonometry for healthy and active males. The DKV control seems to be non-correlated with isolated hip and knee muscles NMR so this suggests it is more about Central Nervous System activity than about isolated muscles NMR.

Highlights

The dynamic knee valgus (DKV) during different sport maneuvers has been widely described as risk factor to develop an anterior cruciate ligament injury
Descriptive data for variables measured in this study are shown at Tables 2 and 3 for neuromuscular response measured by Tensiomyography and MyotonPro respectively
Neither the Myoton nor the Tensiomyography parameters measured in both glutes maximus, biceps femoris, semitendinosus, lateral gastrocnemius and medial gastrocnemius were significantly correlated with frontal plane knee angle during the Single-Legged Drop Jump test (“Annex 1”)

Summary

Introduction

The dynamic knee valgus (DKV) during different sport maneuvers has been widely described as risk factor to develop an anterior cruciate ligament injury. This study aimed to give normative and correlational data about DKV and hip and knee neuromuscular response (NMR) among healthy active males. This study shows normative and correlational data about dynamic knee valgus, tensiomyography and myotonometry for healthy and active males. The dynamic knee valgus seems to be clear[16], but a possible relation between DKV and neuromuscular response (NMR) as contraction time, stiffness, tone or muscular displacement remain unstudied. The aim of this study was: (1) to give normative data about DKV and NMR among active, non-injured males and (2) to study a possible relation between the dynamic knee valgus and hip and knee neuromuscular response as contraction time, stiffness, tone or muscular displacement. We hypothesized that DKV angle could be correlated with hip and knee NMR parameters
